This datasheet presents information related to measurement, distance measuring sensor, signal processing circuit, and distance measuring. There are many information such as characteristics, sensor, and measuring distance are described inside this datasheet.

In the datasheet we can find things around signal processing, distance, and measuring sensor unit. The following are selected from this datasheet:

GP2Y0D340K0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. The output voltage of this sensor stays high in case an object exists in the specified distance range. So this sensor can also be used as proximity sensor.
